摘 要：This paper presents the design of an intelligent fire truck,which is based on the STC89C51 signal chip and realizes tracing,obstacle avoidance,alarm,putting out a fire and so on.The truck uses a model car chassis as a frame,STC89C51 as a microcontroller and including DC motor,flame detector,infrared tracing module with some other circuits.The truck has taken advantage of all the chips and the comprehensive performances in each part reasonably,and the intelligent fire truck can work very well.
